Disposable bag for incinerator ashes and the like



United States Patent O 3,495,762 DISPOSABLE BAG FOR IN CINERATOR ASHESAND THE LIKE Frank A. Verbic, 25114 Hazelmere Road, Beachwood, Ohio44122 Filed .lune 3, 1968, Ser. No. 733,962 Int. Cl. B65d 33/00 U.S. 'CL229-53 1 Claim ABSTRACT F THE DISCLOSURE BACKGROUND OF THE INVENTION Thepresent invention relates to a non-combustible disposable article whichhas utility for use in incinerators, cooking lbroilers, coal burningstoves, and the like.

Taking incinerators as an example, there has heretofore been a problem,not so much in the larger (coml mercial) installations, where anArchimedes screw may suice, but in small home incinerators in removingand/ or disposing of solid products of combustion (e.g., dusty ashes)from a rigid bottom receptacle, such `as a drawer. Similar problemsexist when trying to use a rag, shovel, broom or other tool to disposeof grease at the bottom of a broiler, or ashes in a small coal or Woodburning furnace, stove or fireplace.

An object of the present invention is to provide simple an inexpensivemeans for overcoming the above mentioned difliculties.

BRIEF DESCRIPTION OF THE DRAWING Other objects and advantages willbecome apparent and the invention may be better under-stood fromconsideration of the following description taken in connection with theaccompanying drawing, in which FIG. 1 is a perspective view of adisposable article according to one aspect of the inveniton and shown inplace in a removable drawer-type ash collector of the prior art typeused in some incinerators.

FIG. 2 is a detail showing a preferred accordion type pleat constructionsuggested and claimed for the sides of the disposable article.

FIG. 3 is a perspective view of the disposable article with its pleats(hence sides) extended ready for folding over, to prevent ying dust,etc., when the disposable article is part filled, then removed andplaced (e.g., outdoors) for collection.

FIG. 4 is a perspective View of the disposable article collapsed andmounted on a throwaway backing (e.g., for shipping and store display).

DESCRIPTION OF PREFERRED EMBODIMENT Referring to the drawings FIG. 4shows disposable article 10, attened, as it might be displayed in astore or taken home for eventual use. In FIG. 1, the article is shownhaving a bottom 10B and msy wall portions which have accordion type sidepleats 10S and end pleats 10E. In FIG. 1, the pleats are only part(e.g., 1A) extended, e.g. so that the top of the article 10 is aboutliush with the top of a prior art ash drawer 11 in which it is placed.FIG. 2 is a detail showing the construction of the pleats at a typicalcorner, and FIG. 3

lCe

shows the bag or article of the lnvention pulled way up (pleats attened,or nearly so), for folding over the edges and tieing them as with atwine (not shown) for dust free removal and storage for pick-up.

As in the prior art, the drawer 11 may have a front handle or knob 12 toassist in removing it. The bag 10 can be made of any non-combustiblematerial which is suiiciently flexible for the purpose, aluminum foil ofseveral times the gage used for ordinary kitchen wrapping beingsuitable, as would be lead foil, or tin foil. The article can be made inany suitable manner, e.g. sides might be flat formed integral with aflat bottom, then brought up and surrounded with another layer of sideswith or without another layer of bottom formed integral, and may bewelded or glued with a high ternperature resistant adhesive or otherwisefastened together, before or after the pleating.

For merchandising and sale the article 10 may be loosely adhered to aflat cardboard 14 (see FIG. 4) and the cardboard may have a hang up hole15 and/or suitable display advertising, as desired.

A grate is assumed which, according to usual grate dimensions in anincinerator, is considerably smaller than the pleated edges (so thatdroppings do not compress them) but even if this were not so, as in anopen fireplace or broiler, arrangements can readily be made to fold overside and end tops, or added tabs (not shown), over the top of aremovable drawer or other rigid structure. In any event when the bag,part compressed (as in FIG. 2) is full, its sides are readily pulled upto greatly increase receptacle size and provide added material to closeoff the top of the article and effectively prevent loss of ashes, greaseor whatever.

There is thus provided a device of the character described capable ofmeeting the object Iset forth. In use suicient bulk of the refusematerial (which is light) will ilow to the bag corners to make it easyto pull up the sides and push or twist them together, and the disposableextensible (e.g., accordion pleated) bag allows ready removal withoutloss of its noxious contents, and gives advantages of minimizingatmospheric pollution, and of safety, because of closing 01T of sparksources.

Obviously, instead of the upwardly progressing accordion pleatsillustrated, other pleats or folds could be used.

I claim:

1. A heat-resistant, flimsy-Walled incinerator bag made of a metal foiland having a bottom wall and upwardly lextending therefrom plural sidewall portions which interconnect to define a space open only at the top,each of said side wall portions having means including multiple pleatsfor defining at least three modes of utility for the bag, said modesbeing (1) collapsed to a irst and minimal height for shipment, storageor display, (2) extended to a second and intermediate height forreceiving refuse, ashes and the like while within an incinerator, and(3) extended to a third and greatest height for bag tie-up andsubsequent disposal.
